Bioelectrochemistry. 2023 Nov 11;156:108598. doi: 10.1016/j.bioelechem.2023.108598. Online ahead of print.ABSTRACTOwing to the high mortality and strong infection ability of COVID-19, the early rapid diagnosis is essential to reduce the risk of severe symptoms and the loss of lung function. In clinic, the commonly used detection methods, including the computed tomography (CT) and reverse transcription-polymerase chain reaction (RT-PCR), are often time-consuming with bulky instruments, which normally require more than one hour to report the results. To shorten the analytical period for testing the COVID-19 virus (SARS-CoV-2...

ZnO-rGO-based electrochemical biosensor for the detection of organophosphorus pesticides
Bioelectrochemistry. 2023 Nov 10;156:108599. doi: 10.1016/j.bioelechem.2023.108599. Online ahead of print.ABSTRACTThe accurate determination of organophosphorus pesticide residues is of great importance for human disease monitoring and environmental safety. Numerous detection methods exist, among which sensitive monitoring of organophosphorus compounds using electrochemical sensors has gradually become a research hotspot. This paper used acetylcholinesterase (AChE) as an indicator anchored on a zinc oxide-reduced graphene oxide (ZnO-rGO) composite rich in active sites, in which green non-toxic zinc oxide (ZnO) nanomaterial...

Polyethylene glycol hydrogel coatings for protection of electroactive bacteria against chemical shocks
Bioelectrochemistry. 2023 Nov 8;156:108595. doi: 10.1016/j.bioelechem.2023.108595. Online ahead of print.ABSTRACTLoss of bioelectrochemical activity in low resource environments or from chemical toxin exposure is a significant limitation in microbial electrochemical cells (MxCs), necessitating the development of materials that can stabilize and protect electroactive biofilms. Here, polyethylene glycol (PEG) hydrogels were designed as protective coatings over anodic biofilms, and the effect of the hydrogel coatings on biofilm viability under oligotrophic conditions and ammonia-N (NH4+-N) shocks was investigated. Hydrogel de...

A disposable immunosensor for the detection of salivary MMP-8 as biomarker of periodontitis
Bioelectrochemistry. 2023 Oct 30;156:108590. doi: 10.1016/j.bioelechem.2023.108590. Online ahead of print.ABSTRACTThis work describes the development of a novel voltammetric immunosensor for the detection of salivary MMP-8 at the point-of-care. The electrochemical platform was based on a graphene (GPH) screen-printed electrode (SPE) functionalized by gold-nanospheres (AuNSs) and antibodies against MMP-8 protein (anti-MMP-8). The functionalization with anti-MMP-8 was realized by using 11-mercaptoundecanoic acid (11-MUA), thanks to its ability to give strong sulfur bonds with its -SH end, and to cross-link the -NH2 groups of...
